An image processing apparatus includes MTF correction part for converting an input multilevel image signal obtained via raster scanning into an output multilevel image signal through an MTF correction process, a first bi-level rendition part for performing a bi-level rendition process with respect to the output multilevel image signal so that a first bi-level image signal is produced, a second bi-level rendition part for performing a pseudo halftone rendition process with respect to the input multilevel image signal to generate a second bi-level image signal, a discrimination part for detecting whether a target pixel indicated by the input multilevel image signal is located in a halftone region of an original image or in a bi-level region thereof, and an image synthesizing part for outputting the first bi-level image signal to an output device when the target pixel is detected as being located in the bi-level region, and for outputting the second bi-level image signal to the output device when the target pixel is detected as being located in the halftone region.
